Re: Fetching record of the day

Hello Gary,

What I would do (everyone on list groans) is store the date as a string in
YYYY-MM-DD
format. Actually, I always store dates that way. Should you decide you
want to do that, I have a date validation function I could send you (written
in VB (sorry)).

Good luck
